Abstract A tray for use in vapor-liquid contacting columns in which the vapor flows upwardly through orifices in the tray and liquid flows downwardly through the column. The tray comprises a corrugated surface having spaced ridges running the length of the tray. The corrugated surfaces having a multiplicity of orifices therethrough for vapor flow upwardly through the tray and the orifices are arranged in spaced groups separated from the next adjoining group of orifices by a portion of the tray which does not contain any orifices. A liquid downcomer receives liquid on one section of the tray and another liquid downcomer discharges liquid from another section of the tray, whereby liquid is caused to flow horizontally on the tray surface. Baffles are joined with the corrugated surface and have passageways therethrough. The baffles are positioned on and extend for the entire length of the ridges. The passageways in the baffles have louvers formed thereover and the passageways are arranged in alternating sections along the length of the baffles so that the louvers of one of the alternating sections protrude from one side of the baffle and the louvers of an adjacent section protrude from the opposite side of the baffle. Each section of the passageways are coextensive with a group of orifices in the tray are positioned so that the orifices in the tray are on the side of the baffle corresponding to the outlet-side of the louvered opening in that section. The baffle has thereon a continuous path for liquid flow along the baffle surface to the corrugated tray. A perforated cover joins the baffles. The cover extends from each baffle and joins adjacent baffles to form a multiplicity of parallel, tunnel-shaped enclosures. The cover has thereon a continuous path joining with the continuous path of the baffle for the liquid flow along the surfaces of the cover and baffle to the corrugated surface.
A tray adapted for use in a vapor liquid contacting column in which vapor flows upwardly through said column through orifices in said tray and liquid flows downwardly through said column; said tray comprising (1) a corrugated surface having spaced ridges running the length of the tray, the corrugated surfaces having a multiplicity of orifices therethrough for vapor flow upwardly through said tray, said orIfices being arranged in spaced groups of orifices separated from the next adjoining group of orifices by a portion of the tray which does not contain any orifices; (2) means for receiving liquid on one section of said tray, means for discharging liquid from another section of said tray, whereby said liquid is caused to flow horizontally on the tray surface; (3) baffles joined with said corrugated surface and having passageways therethrough, said baffles being positioned on and extending for the entire length of said ridges, the passageways in said baffles having louvers formed thereover, said louvered passageways being arranged in alternating sections along the length of the baffles so that the louvers of one of said alternating sections protrude from one side of the baffle and the louvers of an adjacent alternating section protrude from the opposite side of the baffle, each section of the passageways being coextensive with a group of orifices in the tray and being positioned so that the orifices in the tray are on the side of the baffle corresponding to the outlet-side of the louvered opening in that section, said baffle having thereon a continuous path for liquid flow along the baffle surface to the corrugated tray; and (4) a perforated cover joining said baffles, said cover extending from each baffle and joining adjacent baffles to form a multiplicity of parallel, tunnel-shaped enclosures, said cover having thereon a continuous path joining with the continuous path of the baffle for liquid flow along the surfaces of the cover and baffle to the corrugated surface.
